Abstract：
The erraticity analysis was performed for the experimental data of multiparticle production in pp collisions at 400GeV/c. New parameters of erraticity are calculated. Com-paring this with the results obtained by Cao Zhen and Rudolph C.Hwa, they have used a soft-interaction model ECOMB to simulate the experiment of hadron-hadron collisions at NA22 energy region, a similarity is seen clearly. This means that the model ECOMB is a soft-interaction multiparticle production model which can reproduce the fluctuations of the event structure of the final states of high energy hadronic collisions.
